Most of all specimens showed well-regulated lamellar eutectic structure; i.e., aluminum rich matrix and CuAl\u2082 lamellae were parallel to the longitudinal direction of the specimen, with few exceptions, e.g., banding structure, degenerate structure produced at the lower solidification rate. Tensile testing of these specimens revealed that the failure occured by a transverse cleavage of CuAl\u2082 platelets and a shear fracture of the matrix between cracks on adjacent CuAl\u2082 platelets. There are many cracks in the CuAl\u2082 lamellae near the final fracture surface, but the distribution of platelet cracks was not uniform. The tensile strength of the specimen obtained was about 24kg/mm\u00b2, and this actual strength showed good agreement with the Kelly-Tyson discontinuous-fiber composite relations.", "subitem_description_type": "Other"}, {"subitem_description": "\u7d00\u8981\u8ad6\u6587", "subitem_description_type": "Other"}]}, "item_1617186643794": {"attribute_name": "Publisher", "attribute_value_mlt": [{"subitem_1522300295150": "ja", "subitem_1522300316516": "\u7409\u7403\u5927\u5b66\u7406\u5de5\u5b66\u90e8"}, {"subitem_1522300295150": "en", "subitem_1522300316516": "Science and Engineering Division, University of the Ryukyus"}]}, "item_1617186702042": {"attribute_name": "Language", "attribute_value_mlt": [{"subitem_1551255818386": "jpn"}]}, "item_1617186783814": {"attribute_name": "Identifier", "attribute_value_mlt": [{"subitem_identifier_type": "HDL", "subitem_identifier_uri": "http://hdl.handle.net/20.500.12000/27536"}]}, "item_1617186920753": {"attribute_name": "Source Identifier", "attribute_value_mlt": [{"subitem_1522646500366": "ISSN", "subitem_1522646572813": "0387-429X"}, {"subitem_1522646500366": "NCID", "subitem_1522646572813": "AN00250785"}]}, "item_1617186941041": {"attribute_name": "Source Title", "attribute_value_mlt": [{"subitem_1522650068558": "ja", "subitem_1522650091861": "\u7409\u7403\u5927\u5b66\u7406\u5de5\u5b66\u90e8\u7d00\u8981. \u5de5\u5b66\u7bc7"}, {"subitem_1522650068558": "en", "subitem_1522650091861": "Bulletin of Science \u0026 Engineering Division, University of the Ryukyus.
